<p>The <a class="link" href="glib-Singly-Linked-Lists.html#GSList" title="struct GSList"><span class="type">GSList</span></a> structure and its associated functions provide a
standard singly-linked list data structure.</p>
<p>Each element in the list contains a piece of data, together with a
pointer which links to the next element in the list. Using this
pointer it is possible to move through the list in one direction
only (unlike the <a class="link" href="glib-Doubly-Linked-Lists.html" title="Doubly-Linked Lists">double-linked lists</a>,
which allow movement in both directions).</p>
<p>The data contained in each element can be either integer values, by
using one of the <a class="link" href="glib-Type-Conversion-Macros.html" title="Type Conversion Macros">Type Conversion Macros</a>,
or simply pointers to any type of data.</p>
<p>List elements are allocated from the <a class="link" href="glib-Memory-Slices.html" title="Memory Slices">slice allocator</a>,
which is more efficient than allocating elements individually.</p>
<p>Note that most of the <a class="link" href="glib-Singly-Linked-Lists.html#GSList" title="struct GSList"><span class="type">GSList</span></a> functions expect to be passed a
pointer to the first element in the list. The functions which insert
elements return the new start of the list, which may have changed.</p>
<p>There is no function to create a <a class="link" href="glib-Singly-Linked-Lists.html#GSList" title="struct GSList"><span class="type">GSList</span></a>. <a class="link" href="glib-Standard-Macros.html#NULL:CAPS" title="NULL"><code class="literal">NULL</code></a> is considered to be
the empty list so you simply set a <a class="link" href="glib-Singly-Linked-Lists.html#GSList" title="struct GSList"><span class="type">GSList</span></a>* to <a class="link" href="glib-Standard-Macros.html#NULL:CAPS" title="NULL"><code class="literal">NULL</code></a>.</p>
<p>To add elements, use <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-append" title="g_slist_append ()"><code class="function">g_slist_append()</code></a>, <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-prepend" title="g_slist_prepend ()"><code class="function">g_slist_prepend()</code></a>,

<p>To remove elements, use <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-remove" title="g_slist_remove ()"><code class="function">g_slist_remove()</code></a>.</p>
<p>To find elements in the list use <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-last" title="g_slist_last ()"><code class="function">g_slist_last()</code></a>, <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-next" title="g_slist_next()"><code class="function">g_slist_next()</code></a>,
<a class="link" href="glib-Singly-Linked-Lists.html#g-slist-nth" title="g_slist_nth ()"><code class="function">g_slist_nth()</code></a>, <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-nth-data" title="g_slist_nth_data ()"><code class="function">g_slist_nth_data()</code></a>, <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-find" title="g_slist_find ()"><code class="function">g_slist_find()</code></a> and
<a class="link" href="glib-Singly-Linked-Lists.html#g-slist-find-custom" title="g_slist_find_custom ()"><code class="function">g_slist_find_custom()</code></a>.</p>
<p>To find the index of an element use <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-position" title="g_slist_position ()"><code class="function">g_slist_position()</code></a> and
<a class="link" href="glib-Singly-Linked-Lists.html#g-slist-index" title="g_slist_index ()"><code class="function">g_slist_index()</code></a>.</p>
<p>To call a function for each element in the list use
<a class="link" href="glib-Singly-Linked-Lists.html#g-slist-foreach" title="g_slist_foreach ()"><code class="function">g_slist_foreach()</code></a>.</p>
<p>To free the entire list, use <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-free" title="g_slist_free ()"><code class="function">g_slist_free()</code></a>.</p>

the elements and reverse the list when all elements have been added.</p>

<p>Makes a full (deep) copy of a <a class="link" href="glib-Singly-Linked-Lists.html#GSList" title="struct GSList"><span class="type">GSList</span></a>.</p>
<p>In contrast with <a class="link" href="glib-Singly-Linked-Lists.html#g-slist-copy" title="g_slist_copy ()"><code class="function">g_slist_copy()</code></a>, this function uses <em class="parameter"><code>func</code></em>
 to make a copy of
each list element, in addition to copying the list container itself.</p>
<p><em class="parameter"><code>func</code></em>
, as a <a class="link" href="glib-N-ary-Trees.html#GCopyFunc" title="GCopyFunc ()"><span class="type">GCopyFunc</span></a>, takes two arguments, the data to be copied and a user
pointer. It's safe to pass <a class="link" href="glib-Standard-Macros.html#NULL:CAPS" title="NULL"><span class="type">NULL</span></a> as user_data, if the copy function takes only
one argument.</p>
<p>For instance, if <em class="parameter"><code>list</code></em>
 holds a list of GObjects, you can do:</p>
<div class="informalexample">
  <table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
    <tbody>
      <tr>
        <td class="listing_lines" align="right"><pre>1</pre></td>

      </tr>
    </tbody>
  </table>
</div>

<p></p>
<p>And, to entirely free the new list, you could do:</p>
